- * The Harvest software was developed by the Internet Research Task
- * Force Research Group on Resource Discovery (IRTF-RD):
- *
- * Mic Bowman of Transarc Corporation.
- * Peter Danzig of the University of Southern California.
- * Darren R. Hardy of the University of Colorado at Boulder.

- * This copyright notice applies to software in the Harvest
- * ``src/'' directory only. Users should consult the individual
- * copyright notices in the ``components/'' subdirectories for
- * copyright information about other software bundled with the
- * Harvest source code distribution.
- *
- * TERMS OF USE
- *
- * The Harvest software may be used and re-distributed without
- * charge, provided that the software origin and research team are
- * cited in any use of the system. Most commonly this is
- * accomplished by including a link to the Harvest Home Page
- * (http://harvest.cs.colorado.edu/) from the query page of any
- * Broker you deploy, as well as in the query result pages. These
- * links are generated automatically by the standard Broker
- * software distribution.

- * The Harvest software is provided ``as is'', without express or
- * implied warranty, and with no support nor obligation to assist
- * in its use, correction, modification or enhancement. We assume
- * no liability with respect to the infringement of copyrights,
- * trade secrets, or any patents, and are not responsible for
- * consequential damages. Proper use of the Harvest software is
- * entirely the responsibility of the user.
- *
- * DERIVATIVE WORKS
- *
- * Users may make derivative works from the Harvest software, subject
- * to the following constraints:
- *
- * - You must include the above copyright notice and these
- * accompanying paragraphs in all forms of derivative works,
- * and any documentation and other materials related to such
- * distribution and use acknowledge that the software was
- * developed at the above institutions.
- *
- * - You must notify IRTF-RD regarding your distribution of
- * the derivative work.
- *
- * - You must clearly notify users that your are distributing
- * a modified version and not the original Harvest software.
- *
- * - Any derivative product is also subject to these copyright
- * and use restrictions.
- *
- * Note that the Harvest software is NOT in the public domain. We
- * retain copyright, as specified above.
- *
- * HISTORY OF FREE SOFTWARE STATUS
- *
- * Originally we required sites to license the software in cases
- * where they were going to build commercial products/services
- * around Harvest. In June 1995 we changed this policy. We now
- * allow people to use the core Harvest software (the code found in
- * the Harvest ``src/'' directory) for free. We made this change
- * in the interest of encouraging the widest possible deployment of
- * the technology. The Harvest software is really a reference
- * implementation of a set of protocols and formats, some of which
- * we intend to standardize. We encourage commercial
- * re-implementations of code complying to this set of standards.
+ * Squid software is distributed under GPLv2+ license and includes
+ * contributions from numerous individuals and organizations.
+ * Please see the COPYING and CONTRIBUTORS files for details.
